Description

The invention relates to the field of shipbuilding and can be used in the construction of hovercraft.

A technical solution is known (RF patent for the invention No. 2060181 dated 06/13/1991, publ. 05/20/1996, B60V 1/04, authors Prikhodko SN, Moiseev VV). The flexible enclosure of the air cushion apparatus comprises elastic panels connected in series with each other. Adjacent lateral edges of the panels are superimposed and fastened by two rows of detachable fasteners. New in design is that the fence is equipped with a seal made in the form of an inflatable chamber. The camera is placed at the junction of the panels, between the edges of the panels and two rows of fasteners. The inflatable chamber can be connected to the air line so that the pressure in the chamber does not exceed the pressure in the air cushion.

The disadvantages of this technical solution: the fence is equipped with a seal in the form of an inflatable chamber accelerates assembly-disassembly, but the inflatable chamber is unreliable in the event of a puncture.

The closest technical solution is a hovercraft (application of the Russian Federation for invention No.2001115733 / 28 dated 05.06.2001, publ. 05/10/2002, B60V 3/06, authors Balandin SA, Mnev Nikolay Viktorovich). The hovercraft comprises a hull, a blower with a steering device, a flexible enclosure of the air cushion area. On the outer sides of the flexible fencing at an angle of 30-60 ° to the vertical plane, strips of elastic material having a wedge-shaped shape, oriented in the direction of movement of the vessel, are placed.

The disadvantages of this technical solution: the impossibility of quick assembly and disassembly due to the inflexibility of the elements of the housing, and the rigid part of the housing is not amenable to quick assembly and disassembly. Strips of elastic material having a wedge-shaped shape, oriented in the direction of movement of the vessel, are unreliable as a hull element due to their elasticity.

The technical result of the claimed technical solution is the creation of a reliable design of the hovercraft with the possibility of quick assembly-disassembly into individual components, with the aim of transporting the components of the vessel in transport.

The technical result is achieved by the fact that the hovercraft comprises a hull, a blower unit with a steering device, a flexible fence for the air bag area, on the outside of the flexible fence there are strips oriented in the direction of the vessel’s movement, and the flexible fence for the air bag area is made bowl-shaped, horizontal plane which is located on top, longitudinal strips are located on the outside of the horizontal plane of the flexible fence and are made in the form of pipes, races laid in rows through a distance of not less than the diameter of the pipes symmetrically relative to the longitudinal axis of the vessel, transversely relative to the longitudinal axis of the vessel, stripes are also horizontally horizontal on top of the longitudinal pipes in the form of pipes at a distance of not less than the diameter of the pipes; both ends of the pipes are equipped with caps in the form of a hemisphere; the intersections of the longitudinal and transverse pipes are equipped with a fixing element, which is two pipes located on the cross, the inner diameter of which is equal to or more than the diameter of the outer longitudinal and transverse pipes, respectively, two pipes of the fixing element are fixedly attached, round-shaped plates are fixed on the top and bottom, the axes of which are located along the axis of intersection of the pipes of the fixing element, round plates are provided with holes through which the lower plate is connected to the outer by means of fasteners on the horizontal plane of the flexible fence, to the inside of the horizontal plane of the flexible fence there is also a similar plate coaxial to the lower plate of the fixation element, and structural elements, discharge unit, chair, extreme fixation elements are connected through fasteners of the upper plate — the pipes located on the cross are provided with plugs , the horizontal plane of the flexible fence is equipped with a sleeve connecting the area of the air cushion with the discharge set vkoy, with the horizontal plane of the flexible fence, longitudinal and transverse pipes, fixation elements form the aircraft body, the pilot is attached to the seat through hook type carbines with fixation; A protective cover is provided for transporting the ship’s components.

The hovercraft contains a hull 1 (Fig 1 ... 6), a blower 2 with a steering device, a flexible fence 3 of the area of the airbag, on the outside 4 of the flexible fence 3 there are strips in the form of tubes 5 oriented in the direction of the vessel. Moreover, the flexible fencing 3 of the area of the air cushion is made bowl-shaped, the horizontal plane 6 of which is located on top. Flexible fence material 3 - Dacron. Flexible fence 3 is stitched with at least two seams, the distance between their edges is at least 5 mm. The ends of the threads (not shown) on the seam are glued, for example, with BF-4 glue. The longitudinal strips 5 are located on the outer side 4 of the horizontal plane 6 of the flexible fence 3 and are made in the form of pipes 5 arranged in rows through a distance of at least the diameter of the pipes 5 symmetrically with respect to the longitudinal axis of the vessel. Transversely relative to the longitudinal axis of the vessel, horizontal strips also are located on top of the longitudinal pipes 5 in the form of pipes 5 at a distance of not less than the diameter of the pipes 5. The pipes 5 are made of high-strength alloys, for example D16T, the diameter and cross section of the pipe 5 is: d40 × 1.5 mm . Both ends of the pipes 5 are equipped with plugs 7 in the form of a hemisphere of material D16M. Plugs 7 are installed in the ends of the pipes 5 by pressing. The intersection points of the longitudinal and transverse pipes 5 are provided with a fixing element 8, which is a cross-located two pipes 9, the inner diameter of which is equal to or more than the diameter of the outer longitudinal and transverse pipes 5, respectively, for example, the diameter and cross-section of the pipe 9 is: d41 × 1.5 mm Two pipes 9 of the fixation element 8 are fixedly attached, round plates 10, 11 are fixedly fixed above and below, the axes of which are along the axis of intersection of the pipes 9 of the fixation element 8.

The vessel operates as follows.

The rise is due to the air supplied under pressure into the enclosed space between the inner side 14 of the horizontal plane 6 and the surface, for example sand, water. The movement of the vessel is due to the reaction force of the jet of air thrown. The air supply to the flexible enclosure area of the air cushion is carried out by a blower 2 with a steering device. The vessel is controlled using the steering device of the blower 2 and the center of gravity of the pilot 16. The center of gravity of the pilot 16 is shifted to the left side and the vessel is rotated to the left. When the center of gravity of the pilot 16 is shifted to the right, the ship is rotated to the right. When the center of gravity of the pilot 16 is shifted forward, the ship moves forward. When the center of gravity of the pilot is shifted 16 back, the ship moves back.
